This reverts commit e4761782e0.
This caused performance problems and jolting of the main UI, because
it broke the important invariant that the height of a Zulip message
should not depend on the content of slow-to-load assets such as
images.
This fixes two issues:
* If you had around 10 distinct emoji reactions on a message (enough
to force a line wrap if the add-your-emoji button was visible),
Zulip would add that button into a new row on hover, jolting the
message feed. This fixes that problem by leaving a blank last line
for the add-your-emoji button.
* We were incorrectly showing the padding for the emoji reactions
region even if there were no emoji reactions, causing messages to
have too much padding.
Add the Zulip logo to the top of the messages feed to show that there
are no more messages to load, or that it is loading more (if the
spinner is still around).
This shows a date on a message header whenever the date of that
message is different than the date of the previous message.
The previous logic was bugged and didn't display dates in headers at
date transition points.
When we change a stream name, we now use the stream id as the
key to find messages we need to live update. This eliminates
some possible race conditions from two users renaming a stream.
This commit introduces message_live_update.js.
The new call stack is this:
subs.update_subscription_properties
subs.update_stream_name
message_live_update.update_stream_name
message_list.update_stream_name
The issue is that we were trying to validate the mentions before
checking that the recipient stream was valid, leading to problems
checking the membership of the stream.
Fixes#3040.
Stream descriptions are now displayed along with the name. The
autocomplete results include streams with matches in the stream
descriptions. Added styling for description in compose.css.
Fixes#2398.
When somebody changes their name, we will now update
the buddy list right away. The old code was trying
to do this through a code path that was designed for
true presence updates, but it was also passing in an
empty array, instead of undefined, which caused it to
fail to invoke the intended part of the codepath to
redraw the buddy list.
Now we just call the new activity.redraw() function,
which does the right thing for the buddy list.
The group PM list was live-updating before this change,
and it continues to live-update as part of the new
activity.redraw() function.
Using the offsetHeight getter is ~2.5x faster than
getBoundingClientRect() on what can be an expensive operation to do in
the hundreds of times.
Note: Tim thinks that this may have been different a few years ago,
since we tested fairly carefully before settling on
getBoundingClientRect, but benchmarks pretty clearly show offsetHeight
is faster today, so we should use that.
The escape key used to be intercepted if the subscription pay display
was set to “block”, but now since we use the class “show” and lack to
hide and show the overlay, the query needs to change.
